A design of optical resonator for donut mode generation

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A resonator to generate a single LGp=0ℓ=1 donut mode with high mode purity up to 99% is reported. The resonator consists of three lens elements and one binary phase element. With such high mode purity, the generated donut laser beam is applicable to a number of studies including trapping and rotating micro particles, non-linear optics, and atomlight interaction. The tolerance of the proposed configuration is discussed, as well methods of compensating for the thermal effects of laser materials while manipulating the resonator in a practical laser diode end-pumped solid state laser system.
